Standing on the shoulders of giants

The phrase "standing on the shoulders of giants" is a metaphor which means "using the understanding gained by major thinkers who have gone before in order to make intellectual progress".

It is a metaphor of dwarfs standing on the shoulders of giants (Latin: nani gigantum humeris insidentes) and expresses the meaning of "discovering truth by building on previous discoveries". This concept has been dated to the 12th century and, according to John of Salisbury, is attributed to Bernard of Chartres. Its most familiar and popular expression occurs in a 1675 letter by Isaac Newton: "if I have seen further [than others], it is by standing on the shoulders of giants."
